Related Projects
Carnegie Mellon University2005-present
RADAR-TM (Reflective Agents with Distributed Adaptive Reasoning-Task Management). Collaborated with a group to design an intelligent prioritizing action list that dynamically reorders tasks along changing time and activity contexts. The reordering behavior is learned from experts' usage of the RADAR action list.
Carnegie Mellon UniversitySchool Year 2004-2005
ATGen-Arch (Architectural Test Generator: Architecture Specification Subsystem). Collaborated with a group to architect a subsystem to specify microprocessor properties relevant to architectural test generators. The project involved the selection of a microprocessor architecture description language (ADL) best suited for generating tests, the design of an efficient internal data model for storing microprocessor architectural properties, and the creation of an application programming interface (API) for querying those properties.
